201105256 九、發明說明： 【發明所屬之技術領域】 本發明係關於菸製品用之多組件濾嘴，以及關於包括 該多組件濾嘴之菸製品。 【先前技術】 帶濾嘴香菸典型地包括以包捲紙（paper wrapper)捲繞 之薛絲塡料桿（rod of tabacco cut filler，又稱爲捲薛桿）’ 及與該捲菸桿以尾對尾（end to end)關係對準且藉由水松 ® 紙（tipping paper)裝接於該捲薛桿上之圓筒狀濾嘴。通常在 沿著濾嘴之一位置，提供呈沿圓周之穿孔（circumferential perforation)之形式之排氣，以將捲菸桿燃燒時產生之主流 菸氣與周圍空氣混合。 在一般帶濾嘴香菸中，濾嘴通常由包捲於多孔性插塞 包捲材中之纖維素乙酸酯絲束（tow)插塞（plug)所構成。然 而，已知亦有具有多組件濾嘴之濾嘴香菸，其包括二個或 多個過濾材料，以去除主流菸氣之顆粒及氣體成分。爲加 〇 強捲菸桿（wrapped tobacco rod)燃燒時產生之主流菸氣之 風味，已知亦可提供具有含風味劑之濾嘴之帶濾嘴香菸。 因此期待提供一種菸製品（例如香菸）用之多組件濾 嘴，當消費者從可抽吸物質桿經濾嘴抽吸時，其於使用期 間可改良對主流菸氣之風味補強。 【發明內容】 依照本發明，提供一種菸製品用之多組件濾嘴，其係 包括：口端段；在口端段上游之包括植物葉片之第一風味 201105256 釋出段；以及在第一風味釋出段上游之包括過濾物質及風 味劑之第二風味釋出段，其中第二風味釋出段之抽吸阻力 大於第一風味釋出段之抽吸阻力，以及第二風味釋出段之 抽吸阻力大於口端段之抽吸阻力。 【實施方式】 在本說明書全文中，「上游」及「下游」係用於說明使 用時，相對於從可抽吸物質桿經多組件濾嘴抽吸出之主流 菸氣之方向，本發明之多組件濾嘴各段之相對位置。 〇 使用時，由於主流菸氣係從可抽吸物質桿經多組件濾 嘴而抽吸出，因此風味由第二風味釋出段中之風味劑釋放 於主流菸氣中。由於主流菸氣係從第二風味釋出段經過多 組件濾嘴通向下游，朝向其口端段，更多風味從第一風味 釋出段中之植物葉片釋放於主流菸氣中。本發明之多組件 濾嘴，可有利地對經該多組件濾嘴所抽吸出之主流菸氣提 供雙重風味強化。

Description of the Invention: [Technical Field of the Invention] The present invention relates to a multi-component filter for smoking articles, and to a smoking article comprising the multi-component filter. [Prior Art] A cigarette with a filter typically includes a rod of tabacco cut filler (also referred to as a "rolling rod") wound with a paper wrapper and a tail pair with the cigarette rod An end-to-end relationship is aligned with a cylindrical filter attached to the roll of the spring by a tipping paper. Exhaust gas in the form of a circumferential perforation is typically provided along one of the filters to mix the mainstream smoke produced by the combustion of the cigarette rod with ambient air. In a typical filter cigarette, the filter is typically constructed of a cellulose acetate tow plug wrapped in a porous plug wrap. However, it is also known to have a filter cigarette having a multi-component filter that includes two or more filter materials to remove particulate and gas components of the mainstream smoke. In order to enhance the flavor of mainstream smoke generated when a burned tobacco rod is burned, it is known to provide a filter cigarette having a filter containing a flavoring agent. It is therefore desirable to provide a multi-component filter for smoking articles, such as cigarettes, which enhances the flavor enhancement of mainstream smoke during use as it is drawn from the smokable substance rod through the filter. SUMMARY OF THE INVENTION According to the present invention, there is provided a multi-component filter for a smoking article, comprising: a mouth end segment; a first flavor 201105256 release segment comprising a plant leaf upstream of the mouth end segment; and a first flavor a second flavor release section including a filter substance and a flavor agent upstream of the release section, wherein the suction resistance of the second flavor release section is greater than the suction resistance of the first flavor release section, and the second flavor release section The suction resistance is greater than the suction resistance of the mouth end section. [Embodiment] Throughout the specification, "upstream" and "downstream" are used to describe the direction of the mainstream smoke extracted from a smokable substance rod through a multi-component filter when in use. The relative position of each segment of the multi-component filter. 〇 In use, since the mainstream smoke is sucked from the smokable material rod through the multi-component filter, the flavor is released from the mainstream smoke by the flavor in the second flavor release section. Since the mainstream flue gas flows from the second flavor release section through the multi-component filter to the downstream, toward the mouth end section, more flavor is released from the mainstream flue gas from the plant leaves in the first flavor release section. The multi-component filter of the present invention advantageously provides dual flavor enhancement to the mainstream smoke drawn through the multi-component filter. The outer diameter of the multi-component filter of the present invention is preferably between about 5 mm and 8.5 mm, and more preferably about 7.8 mm. The total length of the multi-component filter of the present invention is preferably between about 24 mm and about 48 mm, more preferably about 34 mm. The total encapsulated suction resistance (RTD) of the multi-component filter of the present invention, which is measured according to ISO 6565:2002, is preferably between about 100 mm WG (water column pressure gauge) and 180 mm WG. It is preferably about 140mm WG. The mouth end segment preferably has a substantially particle-free phase filtration efficiency or a very low particle size. 201105256 phase filtration efficiency. For example, the mouth end section can comprise a cellulosic material, such as a cellulose acetate tow, or other suitable fiber material with low filtration efficiency. Alternatively, the mouth end section can be comprised of a hollow tube or recess located at the mouth end of the multi-component filter, which is substantially free of filtration efficiency. In the case where the end portion of the multi-component filter of the present invention is a hollow tube or a recess, when the multi-component filter is attached to the smokable substance rod to form a smoking article by, for example, tipping paper, it can be formed. End segment. The mouth end section has a suction resistance, which is preferably measured according to ISO 6565:2002, and is preferably about 20 mm WG or less. The length of the mouth end section is preferably between about 3 mm and about 12 mm, and more preferably between about 6 mm and about 8 mm. When the mouth end section comprises a hollow tube or recess, the length of the mouth end section is preferably between about 3 mm and about 4 mm. The mouth section is used to balance the total suction resistance of the multi-component filter of the present invention to achieve the total suction resistance required for the smoking article comprising the multi-component filter. For example, in the case where the mouth end section includes a cellulose acetate tow plug, 0 can select the denim of each filament and the total denier of the tow to achieve the total demand of the multi-component filter. Pumping resistance. Wherein the mouth end segment comprises a cellulose acetate tow plug, and the cellulose acetate tow has about 5 or more denier per filament. The first flavor release section can include any plant leaf that releases flavor to the mainstream smoke drawn through the multi-component filter. The plant leaves are preferably reduced in size by chipping, cutting or otherwise. Among them, it is more preferable to finely cut the leaves of the plant. Further, the plant blade has a slice width of about 0.4 mm in 201105256. The plant leaves are preferably dried. Further, the water content of the leaves of the plant is preferably about 15% by weight or less. The first flavor release section can include leaves of one or more plants. For example, the first flavor release section can comprise a mixture of tobacco or herbaceous leaves or the like. Wherein the first flavor release section comprises leaves from one or more plants, preferably having about 1 cm wide and 3 cm long leaves after drying. The first flavor release section comprises a plant selected from the group consisting of tobacco, green tea, peppermint, laurel, eucalyptus, basil, sage, verbena, and tarragon Blades are preferred. The first flavor release section is preferably comprised of tobacco, and is preferably comprised of oriental tobacco. The length of the first flavor release section is preferably between about 6 mm and about 12 mm, and more preferably between about 6 mm and about 10 mm. The first flavor release section can comprise a plant leaf applied with an outer layer comprising, for example, a saccharide or a humectant. 〇 The second flavor release section can include any flavor that releases the flavor to the mainstream soda that is drawn through the multi-component filter. Preferably, the second flavor release section comprises a liquid flavor.
